Subject: gunzip does not works with an uppercase suffix

Hi,

its seems that gunzip does not works with uppercase suffixes...

Sample:
gzip pippo.txt
mv pippo.txt.gz pippo.txt.gz_Tape
gunzip -S gz_Tape pippo.txt.gz_Tape
*gunzip: pippo.txt.gz_Tape: unknown suffix -- ignored*

mv pippo.txt.gz_Tape pippo.txt.gz_tape
gunzip -S gz_Tape pippo.txt.gz_tape
* Works as expected *

I'm working with gzip-1.3.5-13.0.1.el5 but the error is the same on Solaris
and is not present on Mac OSX.

Is it a kwown problem? Will it be fixed?

ciao

Thank you for the report. That is a bug, indeed. Here is a small reproducer:

  $ :|gzip > kT && gzip -d -S T kT
  gzip: kT: unknown suffix -- ignored

I have a fix and will post it shortly.

Thanks again. Here's the patch.
I've attributed your email address in the commit log.
If you'd prefer I use a name, tell me what to use soon.
Once I push, that log message cannot be modified.
