* gdb.mi/mi-disassemble.exp, gdb.mi/mi2-disassemble.exp: Remove .*
from test. Escape the | in mi_gdb_test call.
* gdb.mi/mi-basics.exp, gdb.mi/mi-cli.exp, gdb.mi/mi-disassemble.exp,
gdb.mi/mi-pthreads.exp, gdb.mi/mi-stack.exp, gdb.mi/mi2-basics.exp,
gdb.mi/mi2-cli.exp, gdb.mi/mi2-disassemble.exp,
gdb.mi/mi2-pthreads.exp, gdb.mi/mi2-stack.exp: Add extra details to
expected regex's in mi_gdb_test calls.
* lib/mi-support.exp: Remove arbitrary .* from tests.
(mi_gdb_test): Add string_regex variable. Add anchor to main -re.
Fully anchor GDB/MI expected results in mi_gdb_test.
* lib/gdb.exp (string_to_regexp): Escape the ] character.
* gdb.base/sizeof.exp: Remove escape character. Correct test.
