builtin: Reject malformed printf specifications with digits after '*'
Dash doesn't notice when a format string has digits following a * width
specifier.

    $ dash -c 'printf "%*0s  " 1 2 && echo FAIL || echo OK'
    %10s  FAIL

    $ bash -c 'printf "%*0s  " 1 2 && echo FAIL || echo OK'
    bash: line 0: printf: `0': invalid format character
    OK
    $ mksh -c 'printf "%*0s  " 1 2 && echo FAIL || echo OK'
    printf: %*0: invalid conversion specification
    OK

With this patch dash complains about the malformed specifications.

    $ ./src/dash -c 'printf "%*0s  " 1 2 && echo FAIL || echo OK'
    ./src/dash: 1: printf: %*0: invalid directive
    OK

>Add userhost-in-names to manualJune McEnroe 2019-11-11Skip initial NAMES parametersJune McEnroe Channel names can contain '!' so splitting the whole message on it won't work. I hate this code though. 2019-11-11Filter userhost-in-namesJune McEnroe I really want to be writing tests for these functions... 2019-11-10Compare words without copying in filtersJune McEnroe 2019-11-10Separate tags from all targetJune McEnroe 2019-11-10Filter invite-notifyJune McEnroe 2019-11-10Add capsicum note to READMEJune McEnroe 2019-11-10Filter extended-joinJune McEnroe 2019-11-10Expand client configuration documentation and list capabilitiesJune McEnroe 2019-11-10Request all supported caps from serverJune McEnroe 2019-11-10Filter ACCOUNT, AWAY, CHGHOST for incapable clientsJune McEnroe 2019-11-10Rename listen to localJune McEnroe 2019-11-09Remove extended-join and invite-notifyJune McEnroe The remaining caps only generate new commands which can easily be filtered out when sending to clients so will be in the first pass of support. extended-join is probably safe to pass through unaltered, just causing extraneous parameters on JOIN commands, but maybe not. invite-notify reuses the INVITE command where the invited user is not self. 2019-11-09Maintain stateCaps and offer them to clientsJune McEnroe 2019-11-09Parse capabilitiesJune McEnroe The list that I've defined are the ones that I expect to be able to enable probably without any clients breaking... And of course server-time which pounce implements itself. 2019-11-09Avoid the reserved _A names with BIT macroJune McEnroe 2019-11-09Define macro for bit flag enumsJune McEnroe 2019-11-08Check that password is hashedJune McEnroe 2019-11-08Avoid calling getopt_long again after it returns -1June McEnroe On GNU, calling getopt_long again will reset optind back to the first non-option argument, which would cause an infinite loop of reading the same configurtion file forever. 2019-11-08Only change AWAY status for registered clientsJune McEnroe Turns out I did eventually fix this, because I may want to implement "passive clients" for logging or notification stuff, which wouldn't affect AWAY status either. 2019-11-07Just write the example normallyJune McEnroe 2019-11-07Include path in readlinkat errorJune McEnroe 2019-11-07Call clientConsume before clientRecvJune McEnroe This might reduce the frequency of a client getting its own message back because it was behind in the ring when it sent it. 2019-11-06Use -l:filename in Linux.mkJune McEnroe 2019-11-06Fix compat.h for #defined strlcpyJune McEnroe 2019-11-06Allow unsetting LIBRESSL_PREFIXJune McEnroe 2019-11-06Document calico service configurationJune McEnroe 2019-11-06Document SASL EXTERNAL configuration in more detailJune McEnroe 2019-11-06Document pounce service configurationJune McEnroe 2019-11-06Mention Darwin and GNU/Linux in READMEJune McEnroe 2019-11-06Assume LibreSSL from brew on DarwinJune McEnroe 2019-11-06Remove -DNO_EXPLICIT_BZERO from Darwin.mkJune McEnroe 2019-11-06Don't install rc scripts or dirs on LinuxJune McEnroe
