Not a true, I've looked to the ltp-pan.c and it does crude heuristic
that decides if the second part of the line is supposed to be binary
name or a shell script, if it finds any shell redirection characters or
semicolon then it's executed as a script.

gzip01 foo -> gzip01 exit 32;

That one actually works.

Which script are you referring to? There is no ltp-skip.sh in LTP source
code tree.

That is beacuse you have broken the mathing pattern in your patch, the
original one that just deleted the line matched whitespace after the
name.

I'm okay with adding comments to skipfile.

Apart from the broken sed matching regular expression and the skip.sh
that can be replaced with 'exit 32;' this looks reasonably good.
