It is not easy to display a value of point in the middle of a sequence of
text that has the display, composition or intangible
property, or is invisible. Therefore, after a command finishes and returns
to the command loop, if point is within such a sequence, the command loop
normally moves point to the edge of the sequence.
A command can inhibit this feature by setting the variable
disable-point-adjustment:
If this variable is non-nil when a command returns to the command
loop, then the command loop does not check for those text properties, and
does not move point out of sequences that have them.
The command loop sets this variable to nil before each command, so if
a command sets it, the effect applies only to that command.
If you set this variable to a non-nil value, the feature of moving
point out of these sequences is completely turned off.
