show_preview box omits characters when command spans multiple lines

[ednolan]

Reproduction:
On a terminal with a width of 212 characters, run this command (which has 219 characters):

echo 0123456789101112131415161718192021222324252627282930313233343536373839404142434445464748495051525354555657585960616263646566676869707172737475767778798081828384858687888990919293949596979899100101102103104105106107

Then use ctrl-r to bring up atuin.

The preview window shows the command as:

echo 01234567891011121314151617181920212223242526272829303132333435363738394041424344454647484950515253545556575859606162636465666768697071727374757677787980818283848586878889909192939495969798991001011021031
105106107

Omitting two characters around the newline it inserts: 04.

It seems like this is only an issue when style="full", not with style="compact".

Thanks for the report. Looks like our terminal width calculation is a little off
