memory leak in pager

[themoonisacheese]

Describe the bug
gum pager no longer functions correctly as $PAGER, and seems to have a memory leak

To Reproduce
Steps to reproduce the behavior:

1. in 0.15.1: in zshrc, have export PAGER="gum pager"
2. open a command that would automatically use your pager, such as man tail
3. gum pager opens, but no content is displayed, and the entire page is a small pink square with the controls displayed.
4. gum pager uses 100% of 1 CPU, and fills the entire available ram in a few minutes. the server becomes understandably unresponsive and needs to be restarted.

Expected behavior
in 0.14-, this exact configuration worked as expected. man tail would correctly display inside gum pager without issues.

Screenshots

Desktop (please complete the following information):

• OS: Almalinux 8
• Version 0.15.1

note that man tail | gum pager manually works just fine.

hmm interesting, I can reproduce it here. Will take a look and get back to you soon.

Thanks for bringing this up <3

FWIW, the problem seems to be soft-wrap, which was made default in v0.15.

As a workaround, you can use PAGER="gum pager --no-soft-wrap".

this also seems to be fixed in #791

fixed in #827

hey @themoonisacheese, could you try this again on main?

if everything goes well, I'll make a patch release.

Thanks again for reporting this btw 🙏

@caarlos0 seems to work fine with PAGER="./gum pager"(and staying in the repo of course) after building with go build
