Subject: [PATCH] gzip: port zdiff, zless to Busybox
|
|
|
|
Problem reported by Denys Zagorui (Bug#26088).
|
|
* tests/zdiff: Check that diff uses POSIX-format output.
|
|
* zless.in (less_version): Don't exit merely because 'less -V'
|
|
fails; instead, assume 'less' is compatible with an old version of
|
|
the original 'less'. Busybox 'less -V' fails, but apparently its
|
|
'less' works anyway somehow.
|
