Bug: file names capitalised when using gnuplot [9.3 (release_9.3 @ /usr/share/emacs/27.1/lisp/org/)]

Hello,

A bug occurs when plotting data from an Org table using Gnuplot.  An
example is given below.  In the first code block the plot is produced as
expected, but in the second code block (where I have changed a lowercase
"c" to an uppercase "C") gnuplot tries to plot data from a
non-existent file name that consists of all uppercase letters.

Thanks,

Paul

# ================= Start example =====================
#+name: data
|--------+--------|
|      x |      y |
|--------+--------|
| 111.89 |  88.37 |
| 392.12 | 297.33 |
|--------+--------|

This code block works.  It tries to read the data from
"/tmp/babel-stable-462/gnuplot--633772447824105179", which exists.
#+begin_src gnuplot :var c=data :results silent
  reset session
  plot "$c" u 1:2
#+end_src

This code block does not work.  It tries to read the data from
"/TMP/BABEL-STABLE-462/GNUPLOT-2096937058546578295", which does not
exist.
#+begin_src gnuplot :var C=data :results silent
  reset session
  plot "$C" u 1:2
#+end_src
# ================= End example =====================
