I've filed a bug report against Scintilla [1] but it was invalidated
since SciTE, hence Scintilla, could be configured to consider a
"." (dot) character as part of the word in a *.R file. What it needed
was to replace
word.characters.$(file.patterns.r)=$(word.chars.r)

with  
word.characters.$(file.patterns.r)=.$(word.chars.r)

(note the right-hand dot) in the r.properties file. Can this setting be
translated to Geany? 

Thank you
Liviu
