[Message part 1 (text/plain, inline)]

package: gzip 1.8

1. zless util don't support 'less' from busybox package. zless trying to 
figure out the version of 'less', it is launch 'less' with key -V, and 
'less' from busybox don't understand this flag. When i change this 
verification zless works fine with 'less' from busybox.

2. tests/zdiff test fails. 'diff' from busybox and 'diff' from diffutils 
has different output. So i apply attached patch and this works fine.

Thanks, I installed the attached patch to attempt to work around the 
problems you reported.

Could you please explain how ignoring the 'less -V' failure causes zless 
to work on BusyBox? BusyBox 'less' ignores the LESSOPEN environment 
variable, so if zless uses Busybox 'less' then zless should not work 
even if the attached fix is applied.

i think it'd make more sense to update busybox's less to support -V

Sorry, I don't understand.

I don't think my change to zless.in will hurt BusyBox, so I'll leave 
that change in for now. However, I still do not see how 'zless' can work 
with BusyBox 'less'. It seems to me that BusyBox 'less' is incompatible 
with how 'zless' works.

No further comment in five years so I'm closing this old bug report.
