[doc][patch] Minor fixes for some documents

[h_east]

Hi Bram and list,

I atached a patch.

Below, explanation about correction contents.

eval.txt
- L6691: Fixes missing quote after `bufnr`
- L6702: s/or/nor/
- L6775: Remove extra whitespace at end of line.

map.txt
- L1282: Remove extra whitespace at end of line.
- L1410: Same as above

options.txt
- L4136-L4141: Fix to the actual value from `HIGHLIGHT_INIT` at src/option.c
- L4192-L4195: Adjust tab and space
- L4193: s/normal line/selected line/
Because it is explanation of hl-PmenuSel.
- L7343: s/ASCII letter/ASCII alphabet/
Adapted to implementation from src/option.c:L7826
> if (!ASCII_ISALNUM(*p) && *p != '-')

repeat.txt
- L339: mentioned about `!`.

usr_41.txt
- L1062: Remove extra space between `program` and `being`.

Please check this.

I think "letter" is correct here.
