Alter autocompletion settings

Try changing the following in your ~/.inputrc to alter the behaviour of auto completion on application/file names:

set completion-ignore-case on
- performs filename matching and completion in a case-insensitive fashion. The default value is 'off'.

set completion-query-items 200
- number of possible completions that determines when the user is asked if they want to see the list of possibilities. The default limit is 100.

show-all-if-ambiguous
- if set to 'on', words which have more than one possible completion cause the matches to be listed immediately instead of ringing the bell. The default value is 'off'.

visible-stats
- if set to 'on', a character denoting a file's type is appended to the filename when listing possible completions. The default is 'off'.
