[CMD] Fix a typo in filename completion (#3293)

Browse source 
Fix filename completion that could cause a incorrect result when the path
contains "dots". (See also HBelusca@d12169b.)
See CORE-8623 and CORE-1901 (bug introduced in r25896 / 54cf74f).

For example:

- The current directory is `C:\Documents and Settings\Administrator\`, and you
  input `".` and press TAB. The completion result would be `".Administrator"`,
  which even does not exist.

- You input "some(file).ext", and you remove the final quote (or the quote
  and "ext") and you attempt to complete the file name.

- Import two additional fixes from HBelusca@a826730: Fix the search ordering
  in the comparisons between szSearch1, szSearch2 and szSearch3.
