No, the quotes you see are part of the print syntax of the string, not
the string itself. If you query the string for its first character
(ie. the one at index 0) you'll get a '/', not a '"'. Look:
Eval: (buffer-file-name)
"/tmp/foo.txt"
Eval: (aref (buffer-file-name) 0)
47 (#o57, #x2f)
Eval: ?\/
47 (#o57, #x2f)
Eval: ?\"
34 (#o42, #x22)
So (buffer-file-name) does not escape the string. From the elisp
manual:
- Function: shell-quote-argument argument
This function returns a string which represents, in shell
syntax, an argument whose actual contents are ARGUMENT. It
should work reliably to concatenate the return value into a
shell command and then pass it to a shell for execution.
which sounds like what you want.
