mdb command buffer should be larger
In trying to debug ctfmerge of genunix, I can't actually ::run it, because I can't fit all the object files on the command line mdb gives me. It'd be great if that buffer was markedly longer for things like link-editor invocations and this that may have many, many, file arguments.
I could pick this up. What would fit better for mdb: a set max line length using env var or flag, or a buffer that auto-resizes to 2*n? I'd go for the latter but the code as currently written suggests the first. Specifically looking at mdb/mdb_cmdbuf.c uses a confusing mixture of struct field
cmd_linelen and defined constant
