[PATCH] ash: fix command name of shell scripts

[mikma.bbne at lists.m7n.se]

Hello,

when executing a script with ash from busybox in the shebang then the command name will contain "sh" instead of the name of the script as expected. This means you can't use "ps -C <script name>", which is possible if you use bash in the script.

This patch fixes ash, but there may be more uses of bb_busybox_exec_path that need to be fixed, but I'm not sure which. If there are then this patch probably reintroduces the bug that "exe" is used as the command name.
