ca2f831ead hexedit: fixes for redraw and down movement causing SEGV on attempt to access 
"Go to:" command was not updating row position, making next "down" movements
for one screenful print empty lines instead of showing the contents.

If the file is whole pages long, "down" movement at EOF was advancing position
+16 bytes, mapping the next portion (entirely past the end of the file),
then finding out that the new position is beyond the EOF, rolling it back
-16 bytes... ending up with this postion pointing *before* the mapped portion.
Any next access (e.g. "move right" key) SEGVs.

1856740ec0 hush: better names for o_free_unsafe() / o_free(), no logic changes 
o_free() made o_string NULL-initialized,
o_free_unsafe() did not bother reinitializing (expected caller to not need it).
