Subject: manpage unclear regarding $keep
Download (untitled) / with headers
text/plain 1.3k
From <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=125778>: From the second paragraph of the description: The $keep argument is a boolean flag. If true, then the tokens are split on the specified delimiter, but all other characters (quotes, backslashes, etc.) are kept in the tokens. If $keep is false then the &*quotewords() func­ tions remove all quotes and backslashes that are not them­ selves backslash-escaped or inside of single quotes (i.e., &quotewords() tries to interpret these characters just like the Bourne shell). If I understand correctly, the first parenthetical comment is not implying the existence of additional metacharacters understood by ParseWords beyond quotes and backslashes, only noting that *all* characters (including obviously all non-metacharacters) are passed through. If this is correct, then the 'etc.' is somewhat unfortunate and confusing and the parenthetical comment would be more understandable as 'including quotes and backslashes'. The description of the case where $keep is false seems to imply that quotes are indeed the only metacharacters ParseWords concerns itself with, but of course Bourne shell has more of them, and the mention of it is enough to make a person nervous. Trivial patch attached, to be applied if you agree.

So trivial it had a typo in it :) Fixed version attached.
