WikiFormatting - underline bug

[guardian]

I wanted to underline the "Summary:" string:

So I did:

__Summary:__

But what got rendered was:

Summary:__

Instead of:

Summary:

Please note that this ticket description is using html processor to match what's rendered by a buggy wiki engine.

It looks like the html tag is not closed if you put a colon before the closing __ and thus leaks to the end of the paragraph.

e.g.:

__Sumary:__ testing this out

renders as

Sumary: testing this out

test this out.

This was due to the usage of "\w" in the regexp... as we already don't allow that for the last character, I think we can do the same for the first.

If an "_" is really needed in a TracLinks, the quoting syntax can be used, e.g. wiki:"__init__"?

Fixed by r3995.

Ported to 0.10-stable in r4015.
