remote-header-name: chop filename at next semicolon

Browse Source 
The --remote-header-name option for the command-line tool assumes that
everything beyond the filename= field is part of the filename, but that
might not always be the case, for example:

Content-Disposition: attachment; filename=file.txt; modification-date=...

This fix chops the filename off at the next semicolon, if there is one.
