Fish completion fails with quotes in argument #1214
Description
The fish completion script prints ugly traces if quotes are not balanced in the argument.
To reproduce: ./testprog '[TAB]
> ./testprog '- (line 1): Unexpected end of string, quotes are not balanced
./testprog __complete '
^
in command substitution
called on line 35 of file -
in function '__testprog_perform_completion' with arguments './testprog\ \''
called on line 1 of file -
in command substitution
called on line 71 of file -
in function '__testprog_prepare_completions'
in command substitutionThis happens with single and double quotes. Technically the completion still works and offers file completion but the traces makes this unusable.
I also checked this with zsh, bash, #1146 and #1208 but only fish is affected. All other shells offer file completion, which is in my eyes the right thing.
