* prof_parse.c (parse_std_line): Rewrite handling of whitespace in and after
tag, to strip trailing whitespace (per current locale, not just ASCII space
characters), and prohibit any internal space characters in tag names.
(This is not the patch supplied in the bug report; that patch changed the tag
handling to allow spaces in tag names, which we haven't previously allowed. On
the other hand, we haven't specifically disallowed internal tabs or other
whitespace, either, and this patch does so.)
