Subject: Allow renaming multiple files without number if extensions are different
X-Git-Url: https://cloud.milkyroute.net/gitweb/dolphin.git/commitdiff_plain/e8c4d19b7c8d1881dae2a28b1ff7202683648ceb?ds=sidebyside

Allow renaming multiple files without number if extensions are different

Normally, we only allow renaming multiple files if the new file name
contains a contiguous sequence of '#' placeholders, which are then
replaced by numbers.

However, if all extensions are different, we can also rename the files
without such a placeholder because the original extension is preserved
when renaming.

This had been possible some time ago already. That this "accidental
feature" was lost was a side effect of the fix for bug 318942.
