#2134 LexYAML style is broken after 1024 bytes

[Zufu Liu]

The line char lineBuffer[1024] = ""; in ColouriseYAMLDoc() cause it.

There are similar bugs already reported, but for other lexers.

F:\Libs\scintilla\lexers>grep -nr "lineBuffer\[1024\]"
LexBatch.cxx:469:       char lineBuffer[1024];
LexMake.cxx:118:        char lineBuffer[1024];
LexMetapost.cxx:125:    char lineBuffer[1024] ;
LexProps.cxx:82:        char lineBuffer[1024];
LexTeX.cxx:128:    char lineBuffer[1024] ;
LexYAML.cxx:206:        char lineBuffer[1024] = "";

[Zufu Liu]

The 1024 bytes limit will cause another bug for multibyte character in LayoutLine:
line break will be added inside multibyte characters that across the style boundary, each/some part will be drawn as hex code.

[Zufu Liu]

remains three lexers:

D:\notepad2\lexilla\lexers>rg "lineBuffer\[1024\]"
LexTeX.cxx
131:    char lineBuffer[1024] ;

LexMetapost.cxx
128:    char lineBuffer[1024] ;

LexBatch.cxx
120:    char lineBuffer[1024] {};

TeX and Metapost aren't performing byte-level styling with their 1024-byte strings. They are looking for interface=x and %D \\module from the file start to determine the language and set of keywords.
