Starting to test the outputs...
Doing first round of testing:
if (x<0) then\pretzelindent{}\pretzelforce{}begin abs:=-1 end;\pretzeloutdent{}\pretzelforce{}

Doing second round of testing:
if (x<0) then[indent]\pretzelindent{}[force]\pretzelforce{}begin abs:=-1 end;[outdent]\pretzeloutdent{}[force]\pretzelforce{}

Doing third round of testing:
if (x<0) then/*indent*/\pretzelindent{}/*force*/\pretzelforce{}begin abs:=-1 end;/*outdent*/\pretzeloutdent{}/*force*/\pretzelforce{}

Done.
