Currently, the process for getting the common prefix of a list of file
names is a tad too greedy:
1. Find the common prefix of all the strings.
2. Strip the extension from the prefix.
3. Strip trailing punctuation.
Step 2 may strip dots if there’s trailing whitespace and step 3 may
strip useful punctuation (e.g. parentheses). This commit reworks the
process as such:
1. Strip the extension from all the file names.
2. Find the common prefix of all the strings.
3. Trim trailing whitespace.
Fixes #174.
