5965e80a38 tweaks: fold some regexes into one another, for conciseness 
The anchored "^texture" appears to have been a mistake.

d04b0c123e syntax: go: fix word boundary before dot in number literal 
The fragment "\<\." can never match anything because \< matches the
beginning of a word but "." is not a word character.

Replace \< with \B (the empty string not at the edge of a word).

058b9da9b9 syntax: lua: add new and missing standard library functions 
The list now includes all the Lua 5.3 functions listed on
https://www.lua.org/manual/5.3/#index.

Also, remove the coloring of just the library name, so that
only known library functions get highlighted.

38a10a62d0 syntax: lua: support fractional part and exponent for decimal and hex 
As of Lua 5.2: "Hexadecimal constants also accept an optional fractional
part plus an optional binary exponent, marked by a letter 'p' or 'P'"
(see at the end of https://www.lua.org/manual/5.2/manual.html#3.1).

The new regexes do not match a leading nor a trailing dot, but they
are good enough.  Discussion on the mailing list:

091e8faf6d syntax: lua: require at least one digit for hexadecimal numbers 
Since a "0x" by itself is invalid.  Also add word boundaries, so that
e.g. "00x1" (which is invalid) does not get partial highlighting.

Also remove some redundant backslashes from the strings regex.

440a128d25 indenting: keep affecting last line of marked region if it was at first

4f2b01c7e5 syntax: lua: correct the word boundaries on standard library functions 
Functions such as "io.close" should only be highlighted when the
package name ("io") is a word by itself, otherwise code such as
"fooio.close" gets unexpected partial highlighting.
