We can just use the 'field width' for the %s used to print the
alignment, this way we'll get the same result without requiring having a
variable with just lots of space chars.
No way to do that for the dots tho, we still need that variable filled
with dot chars.
# perf report --stdio --hierarchy > before
# perf report --stdio --hierarchy > after
# diff before after

I.e. it continues as:
# perf report --stdio --hierarchy | head -15
# To display the perf.data header info, please use --header/--header-only options.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
