#1043 PDF title pattern generates filename errors

[Anonymous]

Attaching a pdf to a reference, the new beta (2.8) allows you to define a renaming pattern that generates a filename for the attached pdf based on the bibtex key and the title of the reference. Though this is extremely helpful, it cannot handle colons well - which is a problem on Windows machines.

A title of "Recent Findings in Some Fields: Thoughts and Ideas." should not turn into "Recent Findings in Some Fields: Thoughts and Ideas..pdf"
Better would be:
"Recent Findings in Some Fields - Thoughts and Ideas.pdf" that is: replace colon automatically with a hyphen and skip the last point in titles.

Thank you very much!
