Hi,

Lars-Dominik Braun <lars <at> 6xq.net> skribis:

>> No control sequences if you do “unset LESS” before hand, right?
>> I think we’ll just override ‘LESS’ unconditionally as shown below.
> yes, and the patch fixes the issue.

Hi,

when using `guix search python2-xcffib` on a foreign distribution (Gentoo) not
all control sequences are stripped by the pager (see location and license):

`guix search python2-xcffib | less` works fine, `unset`ting the environment
variable $LESS or setting it to 'FrX' (i.e. what guix does when it’s missing)
fixes the issue too, so I’m a little puzzled. Some more information:

---snip---
$ env | grep -i less
LESS=-R -M --shift 5
LESSOPEN=|lesspipe %s
PAGER=/usr/bin/less
$ less --version
less 551 (PCRE2 regular expressions)
