Remove the terminal frontend flag TERMP_NOLPAD.

In columnated contexts (.Bl -column, .Bl -tag, .IP, .TP, .HP etc.), do not
pad after writing a column.  Instead, always pad before writing content.

In itself, this change avoids:
 - writing trailing whitespace in some situations
 - with .fi/.nf in .HP, breaking lines that were already padded

It allows several bugfixes included in this patch:
 - Do not count backspace as a character with positive width.
 - Set up proper indentation when encountering .fi/.nf in .HP.
 - Adjust the .HP indentation width to what groff does.
 - Never unlimit the right margin unless in the final column.

This reduces the groff/mandoc-differences in base by nearly 20%,
from 89k to 72k lines of diffs.
