create-pot-files.sh misses strings in .hlp files, generates outdated headers in .pot files

I ran the bin/create-pot-files.sh script to begin with my own translation. It gave me several files to work with, one of which was civicrm-helpfiles.pot .

I wanted to make changes to the strings in templates/CRM/Contact/Form/Domain.hlp file but the civicrm-helpfiles.pot file did not contain all the strings present in it. In fact, it contained only 2 of 5 strings enclosed in

{ts} in that file. I am guessing that this is happening across other .hlp files too.

All those lines skipped did seem to contain unacceptable characters, but I am not sure about that. Because the bin/create-pot-files.sh script throws a lot of warnings about "Invalid marker content" in ts() functions all over the code, but none about {ts}

or this location.

Secondly, line 19 of bin/create-pot-files.sh still writes "CiviCRM 2.2" to the .pot files' headers. Maybe it should be set to "CiviCRM 3.0" in this release.
