[PATCH v4 0/8] gdb: split array and string limiting options

["Maciej W. Rozycki" <macro@embecosm.com>]

Hi,

 I have retained the original subject for the cover letter for threading 
purposes, however this has now otherwise become a small patch series and 
Andrew's original change has a different heading now.

 This is v4 for Andrew's original proposal to split the `set/show print 
elements' options into two, so that there are separate `set/show print 
characters' options to control how many characters of a string are 
printed.  Following earlier discussion for compatibility with existing 
setups I have implemented a mechanism to make the `set print characters' 
setting follow that of `set print elements' by default.  Consequently what 
was a single change has now grown into a patch series.

 In this series I fix some preexisting issues in the area first, implement 
the general framework for extra literals used with integer settings second 
and then add the original change for `set print characters' from Andrew, 
adjusted accordingly, followed by a testsuite update as a separate change. 
This is so as to ensure the semantics of the existing `set print elements' 
knob hasn't changed in the default `set print characters' state (a small 
update for the test suite is nevertheless included with the `set print 
characters' command proper, because inevitably the relevant commands that 
list commands now print additional entries, plus there's been a minimal 
test case update included for the verification of setting defaults).

 I think there's little more to say here except that changes in the series 
have been individually regression-tested with a native `x86_64-linux-gnu' 
configuration, and that I have visually examined the result of changes to 
the GDB manual in the info and PDF formats.

 See individual change descriptions for details.

 OK to apply?
