* | win32: shrink code to detect .exe filesRon Yorston2017-08-301-9/+4
| | | | | | | | | | | | | | | | Add a function (has_exe_suffix) to replace explicit code to check if a filename ends with '.exe. or '.com'. Also shrink code that checks for '.exe' or '.com' on PATH in shell's find_command function.
* | Revert "ash: allow long-running nofork applets to be interrupted"Ron Yorston2017-08-221-9/+1
| | | | | | | | | | | | | | This reverts commit f5051d07f196a8ff7aeaae762333d5aa2b824088. Upstream made 'yes' and 'seq' NOEXEC rather than NOFORK which also solves the problem, though NOEXEC doesn't provide any gain in busybox-w32.

So errors such as ${#&} are not caught. This patch fixes that by moving the is_special check to just before we print out the special variable name.
