* Fix multi-line prompts when right prompts are usedJune McEnroe2020-12-23
| | | | | | editline does not render a multi-line PS1 correctly when RPS1 is also set. To work around this, return only the last line of the cached prompt to editline, and print the leading lines separately inside setprompt.
* Add RPS1 and RPS2 right prompt variablesJune McEnroe2020-12-23

* Cache the expanded prompt for editlineJune McEnroe2020-12-23
| | | | | | | | | | | | | | | | | | | Previously, the prompt would be expanded every time editline called the getprompt callback. I think the code may have been written assuming that editline only calls getprompt once per prompt, but it may actually call it many times, for instance every time you type backspace. This results not only in slower editing from expanding complex prompts repeatedly, it also consumes more and more stack memory each time getprompt is called. This can be seen by setting PS1 to some command substitution, typing many characters at the prompt, then holding backspace and observing memory usage. Thankfully all this stack memory is freed between prompts by the stackmark calls around el_gets. This change causes prompt expansion to always happen in the setprompt call, as it would when editline is disabled, and a cached copy of the prompt is saved for getprompt to return every time editline calls it. Since getprompt is no longer doing expansion, the stackmark calls surrounding el_gets can be removed.
* Bind libedit's secret filename completion functionJune McEnroe2020-12-22
| | | | | | | | | | Check if the FreeBSD (and by extension macOS) _el_fn_sh_complete version of the function exists, which does shell escaping of completed filenames before _el_fn_complete learned to. Tab is bound after calling el_set() and el_source() since the default bindings set tab to something else, and it should always be filename completion in the shell.
* Build with libedit by defaultJune McEnroe2020-12-22

* Fail if building --with-libedit and can't find libeditJune McEnroe2020-12-22
| | | | | Previously, configure --with-libedit would only fail in the case where libedit is available but its header file histedit.h is not.
