ui-tree: use "sane" isgraph()
Git's git-compat-util.h defines a "sane ctype" that does not use locale information and works with signed chars, but it does not include isgraph() so we have included ctype.h ourselves. However, this means we have to include a system header before git-compat-util.h which may lead to the system defining some macros (e.g. _FILE_OFFSET_BITS on Solaris) before git-compat-util.h redefines them with a different value. We cannot include ctype.h after git-compat-util.h because we have defined many of its functions as macros which causes a stream of compilation errors. Defining our own "sane" isgraph() using Git's sane isprint() and isspace() avoids all of these problems. Signed-off-by: John Keeping <john@keeping.me.uk>
