fix(pager): set COLUMNS env var for pager width detection#930
Conversation
Sets the COLUMNS environment variable when spawning the pager pipeline,
allowing pagers to detect the preview pane width. Users with delta's
side-by-side mode can reference this in their config:
[select]
pager = "delta --width=$COLUMNS"
Fixes #924
