Hi, with the change several days ago, I see some texts were added in the gdb manual to tell the user about changing how file names are displayed.

These changes were under the frame/backtrace section of the manual, but those options were in-fact affect on other part of the command response. E.g. the breakpoint command response.

E.g.: set filename-display absolute will affect the result.

[debug]> break "E:/code/cb/test_code/mortenr2012-01-15/main.cpp:16"
[debug]Breakpoint 2 at 0x4016ef: file E:\code\cb\test_code\mortenr2012-01-15\main.cpp, line 16.

So, please mention or add some texts for this kind of information. Thanks.
