Subject: 	* top.c (command_line_input):  Only strip out an initial #-comment.
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=f2ed3a80bbee4ea7e133c4b7ae56fcae3cf8699c;p=deliverable%2Fbinutils-gdb.git

	* top.c (command_line_input):  Only strip out an initial #-comment.
	Looking for internal comments is language-specific (breaks Scheme).
