DO /L and quoted arguments?

[AnrDaemon]

I just stumbled upon a problem. I wanted to process some strings passed as parameters, but the result was somewhat unexpected.
I've reduced the issue to this Simple Test Case:

SET i=0
DO EXT IN /L .sh ".bad sh"
  SET i=%@EVAL[%i+1]
  IFF "%@LEFT[1,%[EXT]]" == "." THEN
    ECHO "%[EXT]"
  ENDIFF
ENDDO
ECHO Did %i runs.

Contrary to the expectation, the cycle runs 3 times and only display one extension. (The latter is not actually suprising, considering the former.)

Is this considered normal behavior?

The parameters following DO x IN /L are strings, not filenames. Each parameter will be assigned in sequence, from left to right, to the loop control variable on consecutive passes through the loop. /L will not treat double quotes as delimiters; use /Q if you want to pass arguments with embedded white space.

do e in /l .sh ".bad sh" (echo %e)
.sh
".bad
sh"

do e in /q .sh ".bad sh" (echo %e)
.sh
".bad sh"

There's no /Q option for TCC/LE

[~\Documents\Bugs\TCC]$ "do-_Q-stc.btm"

TCC LE  14.00.9 x64   Windows 7 [Version 6.1.7601]
Did 0 runs.

And RT doesn't unquote parameters.

You could use @unquote to unquote the parameters.

do e in /q .sh ".bad sh" (echo %@unquote[%e])
.sh
.bad sh

There's no /Q option for TCC/LE

/Q was added in TCC 16.

Yes, I know. It's just extra work when I already explicitly know that paramerets may have been quoted.
And it is @UNQUOTES[] rather than @UNQUOTE[], since the latter destroys inner quoting of the string.
