The custom prefixes are only the first character, which you 
correctly identified.

The second (and further) characters are already part of the GDB/MI
protocol, for details see

https://sourceware.org/gdb/onlinedocs/gdb/GDB_002fMI-Command-Syntax.html#GDB_002fMI-Command-Syntax

Note that the format described there is mostly, but not always
precisely what GDB produces in reality.

The interface to other backends (LLDB, CDB) use essentially the same
markup, even if it is nowhere native to them.
