Stephan Bergmann cc20344010 tdf#111313: Honor bWriteNoLenParam in !bCompatibility, too 
e8deba22e8 "INTEGRATION: CWS ab26" had added
the bCompatibility case with all the argument checking ("2006/05/04 08:33:46 ab
1.66.10.3: #111951# Changed Mid runtime behaviour only for
CompatibilityMode(true)"), and it was probably an oversight that, for
!bCompatibility, it left the bWriteNoLenParam case (triggered by Basic code like

  s = "abc"
  Mid(s,1) = "d"

) calling OUStringBuffer::remove with an illegal argument of len=-1.

Change that so that only setting ERRCODE_BASIC_BAD_ARGUMENT is controlled by
bCompatibility, while all the other checks (that are probably all necessary to
not call rtl string functions with illegal arguments) are done in both modes.

Also, the check

  nStartPos + 1 > nArgLen

should probably be

  nStartPos > nArgLen

instead, as nStartPos has already been decremented from the one-based Basic
index to the zero-baesd rtl string index.

This implements a macro language that, when in VBA compatibility mode,
is intended to be interoperable with Visual Basic for Applications,
allowing people to run macros embedded in their documents.
