Morthimer McMare cd8355bfa8 Ticket #4556: color definitions in the "c.syntax" highlight file. 
Definitions are provided for:
- Various punctuation (divided into 9 groups);
- Preprocessor;
- Keywords;
- Data types;
- Data type qualifiers;
- Numbers (can be different for the integer, hexadecimal, octal and floatpoint representations);
- Strings and escaped characters;
- Comments (with keywords like "TODO:");
- Labels.
In total 32 "defines"...

Based on the original "c.syntax" file, this version includes most of the content from C89..C23.

Closes MidnightCommander/mc#203.

# Syntax rules for the C (and partially C++) programming languages.
#
# Rewritten and extended with defines by Morthimer McMare
# <mailto:morthimer_second@list.ru>
#
# Tab size: 4.
# Feel free to improve the highlighting file.
#
# Date:
# Initial 2024.04.24;
# Updated 2024.06.26 (first public release. Classic Midnight Commander C-syntax theme set by default, added keywords from the C23 standard).
#
# For the default (blue) background.
# The colors almost match the original "c.syntax" file, slightly extending it:

# I think this highlighting is easier for the eyes for the black background themes. Can be also used with the blue background:
