Xchanges to MicroEMACS v3.8i
X
XSorry I couldn't do a context diff on the system with the source. These
Xconsist of the name of the module, the reason for the change, given as
Xcomments, and the actual diffs. These represent some changes I found
Xuseful. With the exception of the change to the 'word' logic, these will
Xdo nothing but eliminate compiler warnings.
X----------------------------------------------------------------
Xestruct.h
X# This change is to keep the VAX C compiler from complaining about
X# undefining 'abs'. It complains on every compile, and on the link
X# once per module. Enough!
X269a270
X> #ifdef abs
X270a272
X> #endif
X
Xtermio.c
X# this avoids a message from the BSD compiler about "statement
X# not reached"
X462c462
X< #endif
X---
X> #else
X463a464
X> #endif
Xword.c
X# This causes emacs to treat words the way vi does. Delete word now has
X# the following logic:
X# - if the cursor is in a word, delete the word and all following
X# whitespace
X# - if the cursor is not in a word delete characters up to the next word
X#
X# This matters for expressions like "abc/(def+ghi)", where the original
X# logic would delete from 'a' in 'abc' to 'd' in 'def', dropping the
X# operators on the way. With this change the word deleted is 'abc' only,
Xprobably what is intended.
