[Crash-utility] Patch to add comments

[Imap]

Hello Dave,
A small cosmetic pach to add comments in the crash flow.
Of course we may use !# to do this, but to call a shell just for a comment seems rather hard ?



With !#, we have:

crash> !#
crash> !# sysrq-triger
crash> !#
crash> file_operations 0xffffffff81643300
struct file_operations {
  owner = 0x0, 
  llseek = 0xffffffff81166b90 <noop_llseek>, 
  read = 0, 
  write = 0xffffffff812fa4b0 <write_sysrq_trigger>,
[...]
}After the introduction of the command #, we just have: 

crash> #
crash> # sysrq-triger
crash> #
crash> file_operations 0xffffffff81643300
struct file_operations {
  owner = 0x0, 
  llseek = 0xffffffff81166b90 <noop_llseek>, 
  read = 0, 
  write = 0xffffffff812fa4b0 <write_sysrq_trigger>,
[...]
}
