Update version to 1.11.1

Cast ctype.h inputs to unsigned char

Fuckings to glibc, jesus christ that code was a nightmare

Read glibc's ctype.h and then compare it to musl's src/ctype/isalpha.c

string.c: swap calloc arguments

Suppress sentence spacing after end-of-sentence characters.

This should fix the inconsistent spacing issue mentioned in [1]. I also
fixed a spacing in issue in the man page.

Fix parsing of line breaks without newline

Add basic working tests for line breaks parsing

Allow subsection in preamble

Subsections are useful in case on name conflicts within a section.
Typically man pages in distributions are using the 'p' subsection.
They are also needed for the man pages of wrapper commands for example.

Section needs to be explicitly defined

The absence of value between the section parentheses resulted in the
section being 0 (header files), which is unlikely to be the one wanted

Update version to 1.10.1

Fix `date --date` dependent test

This test depends on a nonportable option for date(1). I am not sure
that there is a good portable way to do this, so I just directly
included the seconds since epoch that it would have computed. We're
testing scdoc, not testing the local system's date command.

Fix timezone-dependent tests

These tests fail depending on timezone and current time if the date
differs from the UTC date. This was remedied by using `date -u`, which
is POSIX.

Expand preamble written to man page output

Replace str_t with struct str
