[bug-gettext] [feature request] msggrep --reference

[Raphaël]

Hi,

msggrep currently support the following filters:
* msgctxt
* msgid
* msgstr
* comment
* extracted-comment

This last missing bit is the *reference*.
I'm in a case of a web application where I want to extract references
matching /content/, /settings/, ... and the reference is the only usable
criterion.
Would it be complex to introduce such a filter to msggrep ?



thanks
