dyndbg: accept 'file foo.c:func1' and 'file foo.c:10-100'
Accept these additional query forms:
echo "file $filestr +_" > control
path/to/file.c:100 # as from control, column 1
path/to/file.c:1-100 # or any legal line-range
path/to/file.c:func_A # as from an editor/browser
path/to/file.c:drm_* # wildcards still work
path/to/file.c:*_foo # lead wildcard too
1st 2 examples are treated as line-ranges, 3-5 are treated as func's
Doc these changes, and sprinkle in a few extra wild-card examples and
trailing # explanation texts.
