Describe the bug

When you are within a search in the ROOT prompt (CTRL+R), pressing right arrow or left arrow selects the current match, but also introduces stray characters [D, [C or similar. Which have then to be erased by hand.
Something similar is found if you press Ctrl+Right_arrow or Ctrl+Left_Arrow

Expected behavior

The same, but without the stray characters being added.

To Reproduce

  • Open ROOT prompt
  • CTRL+R
  • Type something
  • Press right arrow

[textinput] Do not assign ESC a special meaning on history search mode
bed9e2c 
UNIX terminals, e.g. vt100, send escape sequences for many special
key combinations. Entering the history search mode assigned a specific
meaning to the ESC character and disabled the processing of escape
sequences, thus accidentally printing some characters that are part
of a CSI.

As a workaround, avoid changing the meaning of ESC; users can still
use the well-known `ESC ESC` sequence (or any other editor command,
e.g. move left/right) to exit the history search mode.

Closes issue root-project#10209.
