Bug Description
Hello, I would normally PR straight to the source, but I could not work out where that is.
watch seems to react to terminal resizes (good). But this is not documented in the man page. This is an issue if the user actually wants that command to only run at the specified cadence. IE it is expensive or dangerous. A flag to disable would be nice, but really just documenting is enough.
Confirm with:
watch -n60 'echo $(( $(cat f) + 1 )) | sponge f; cat f'
and resize your window
