Changeset reference not processed at beginning of bugnote

[dregad]

Given a bugnote with the following contents, Source Integration does not transform it into a link to the given commit.

c:repo:sha:

If the reference is preceded by whitespace, then it works properly

test c:repo:sha:

This is a follow-up of #204 - the updated regex (see commit 3dbec81) does not fully take into consideration the fact that the string received in SourcePlugin::display_formatted() has already been processed by the MantisCoreFormatting plugin.

The ^ in the regex's lookbehind intended to match the beginning of the string, does not work because in in the example above, the actual value of $p_text parameter is

<p>c:repo:sha</p>

So the character preceding the changeset reference is neither whitespace, nor the string's beginning so there is no match.

This fix should have been committed separately, but was inadvertently included in c888810 (-> fixed in 2.4.1).
