strip leading/trailing white space and following inline comments from value

strip leading/trailing white space and following inline comments (if separated by at least a space or a tab) from value.

I am no regexp expert so am not 100% sure if this is correct. Randomly ping @StefanKarpinski @tanmaykm @daviddelaat @ViralBShah which might have more experience or objections as they made commits to this package.

I tried it out and it seems to work so I would merge and tag if there are no objections.

This doesn't seem right. For example, your regex is wrong because [#,;] matches a # or ; or ,.

Also, any solution of this form is going to be brittle because ini files can contain strings. e.g. foo="###" is a perfectly valid line, and the # does not begin a comment.

Ok thanks for reviewing Steve! Then better not merging unless a proper solution is proposed.
