 `patch' Quoting Style
 ---------------------
 
    When `patch' outputs a file name in a diagnostic message, it can
 format the name in any of several ways.  This can be useful to output
 file names unambiguously, even if they contain punctuation or special
 characters like newlines.  The `--quoting-style=WORD' option controls
 how names are output.  The WORD should be one of the following:
 
 `literal'
      Output names as-is.
 
 `shell'
      Quote names for the shell if they contain shell metacharacters or
      would cause ambiguous output.
 
 `shell-always'
      Quote names for the shell, even if they would normally not require
      quoting.
 
 `c'
      Quote names as for a C language string.
 
 `escape'
      Quote as with `c' except omit the surrounding double-quote
      characters.
 
    You can specify the default value of the `--quoting-style' option
 with the environment variable `QUOTING_STYLE'.  If that environment
 variable is not set, the default value is `shell', but this default may
 change in a future version of `patch'.
