Author: jilles Date: Fri Oct 16 16:17:57 2009 New Revision: 198173 URL: http://svn.freebsd.org/changeset/base/198173 Log: sh: Show more information about syntax errors in command substitution: the line number where the command substitution started. This applies to both the $() and `` forms but is most useful for `` because the other line number is relative to the enclosed text there. (For older versions, -v can be used as a workaround.)
