Subject: cli: support bracketed paste
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=00fa8256b5c9b3ccbccbdfa8026bce2efd66d630;p=u-boot.git

cli: support bracketed paste

Some consoles use CSI 200~ and CSI 201~ to bracket inserts. This leads
U-Boot to misinterpret the inserted string. Ignore these escape sequences.
