[PATCH] urls.txt: Use substitution to escape square brackets

[Junio C Hamano <junkio@cox.net>]

Alp is right -- the comments in [attributes] section after the
definition do appear in the output, even with asciidoc 7.1.2, so
here is a replacement proposal from me.

The one by Alp is an easy work-around, but I do not want to
worry about potential, unintended, breakages that might be
caused by changing delimited blocks to literal paragraphs (and
it changes the resulting rendering from the original).

From: Jonas Fonseca <fonseca@diku.dk>

This changes "[user@]" to use {startsb} and {endsb} to insert [ and ],
similar to how {caret} is used in git-rev-parse.txt.

[jc: Removed a well-intentioned comment that broke the final
 formatting from the original patch.  While we are at it,
 updated the paragraph that claims to be equivalent to the
 section that was updated earlier without making matching
 changes.]
