Error if the file name includes a single quote

[Leandros]

The arguments to git are quoted in single quotes to allow file names with spaces, but this proves a problem, since files with ' in their names are now producing an error (for the imaginary file This doesn't work.txt):

Error: Could not run 'git --git-dir='/Users/redacted/workspace/redacted/.git' --work-tree='/Users/redacted/workspace/redacted' show master:'redacted/redacted/redacted/This doesn't work.txt' | LC_ALL=C file --mime-type -' => sh: -c: line 0: syntax error near unexpected token `('
sh: -c: line 0: `git --git-dir='/Users/redacted/workspace/redacted/.git' --work-tree='/Users/redacted/workspace/redacted' show master:'redacted/redacted/redacted/This doesn't work.txt' | LC_ALL=C file --mime-type -'.
