This is because blindly highlighting tcsh10" statements as keywords caused way too many false positives. Eg:11"12" 	set history=20013"14" causes history to come up as a keyword, which we want to avoid.15 16" Quit when a syntax file was already loaded17if exists('b:current_syntax')18  finish19endif20 21let s:oldcpo = &cpo22set cpo&vim " Line continuation is used23 24syn iskeyword @,48-57,_,192-255,-25 26syn case match27 28" ----- Clusters ----- {{{129syn cluster tcshModifiers	contains=tcshModifier,tcshModifierError30syn cluster tcshQuoteList	contains=tcshDQuote,tcshSQuote,tcshBQuote31syn cluster tcshStatementEnds	contains=@tcshQuoteList,tcshComment,@tcshVarList,tcshRedir,tcshMeta,tcshHereDoc,tcshSpecial,tcshArgument32syn cluster tcshStatements	contains=tcshBuiltin,tcshCommands,tcshIf,tcshWhile33syn cluster tcshVarList		contains=tcshUsrVar,tcshArgv,tcshSubst34syn cluster tcshConditions	contains=tcshCmdSubst,tcshParenExpr,tcshOperator,tcshNumber,@tcshVarList35 36" ----- Errors ----- {{{137" Define first, so can be easily overridden.38syn match tcshError contained '\v\S.+'39 40" ----- Statements ----- {{{141" Tcsh commands: Any filename / modifiable variable (must be first!)42syn match tcshCommands	'\v[a-zA-Z0-9\\./_$:-]+' contains=tcshSpecial,tcshUsrVar,tcshArgv,tcshVarError nextgroup=tcshStatementEnd43 44" Builtin commands except those treated specially.
